Final answer:
Data transfers between Azure services in different regions usually incur charges based on outbound data transfer rates. Inbound data transfers are generally free, but outbound data transfers can be costly and should be considered in cloud architecture.
Step-by-step explanation:
The student has asked whether data transfers between Azure services located in different Azure regions are always free. The statement is false. Though within the same region data transfer might be free, transferring data between different regions usually incurs charges. These charges are based on the outbound data transfer rates defined by Azure, which means that you will be charged for the data that leaves an Azure region heading towards another region. However, inbound data transfer (data coming into Azure regions) is typically free. It's important to note that data transfer costs can become significant and need to be taken into consideration when architecting solutions on the cloud.
